Both of the above trigger an assertion, it seems to be in pvgrub code
(because I doubt minios has anything kexec related):

root  (hd0,0)

 Filesystem type is ext2fs, partition type 0x83

kernel  /boot/vmlinuz-3.16.0-4-686-pae root=UUID=482efee7-e0f0-453e-bb8e-000bfc

In this case it seems like the guest didn't suspend, but AFAICT the
guest is up and running. No errors on the serial console. It's on the
x16 migration.

This one is worse, there's the following error from libxc:

xc: detail: Frames: 105472/1045504   10%
xc: detail: Frames: 115712/1045504   11%
xc: detail: Frames: 125952/1045504   12%
xc: detail: Frames: 136192/1045504   13%
xc: error: Failed to get types for pfn batch (14 = Bad address): Internal error
xc: error: Save failed (14 = Bad address): Internal error

The guest seems to be alive afterwards.

Roger.
